Disclosed is a pump (1) that employs a magnetic coupling to connect the motor (2) to the impeller (20). A simplified structure within the pump (1) casing is employed to enable the easy removal of the pump's impeller (20) and bushings and/or bearings (24). In one embodiment of the invention, the exterior surface of the impeller (20), including its attached magnets (16), is encased in a plastic bushing (56, 58, 60) material. Surrounding the impeller (20) is a tubular bushing (58) that may at times come into contact with the bushing material of the impeller (20).
